Subject: staging: comedi: amplc_pc263: Remove thisboard and devpriv macros
X-Git-Tag: Ubuntu-5.13.0-19.19~24149^2~983
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=04d66968b34e3e22a524064df387c9fe906c6efa;p=mirror_ubuntu-jammy-kernel.git

staging: comedi: amplc_pc263: Remove thisboard and devpriv macros

The 'thisboard' and 'devpriv' macros rely on a local variable having a
specific name and yield pointers derived from that local variable.
Replace the macros with local variables wherever they occur.
